Kunes fought in the Black Army as a great-swordsman, typically with the Forlorn Hope, and was involved in action twice against Ottoman Janissaries, during which his courage was noted. Ironically, his resulting promotion to feldweibel cost him dearly. He was stationed on one of the towers in Belgrade on the last day of the siege so he missed out on the final battle and looting, much to his chagrin. Like Jan de Kriek, Kunes often has elaborate plans ready for various situations that come up, but is usually overruled by the older members of the group as being too bold. He and Jan sometimes argue and have had a few heated exchanges over strategy. It doesn’t help that they barely understand each other.
